Webb8 maj 2014 · The pH is measure of acidity of a solution whereas the pOH is a measure of basicity of a solution. The two expressions are opposites expressions. As the pH increases the pOH decreases and vice versa. Both values equal 14. Webb6 mars 2024 · pH is an expression of hydrogen ion concentration in water. Specifically, pH is the negative logarithm of hydrogen ion (H +) concentration (mol/L) in an aqueous solution: pH = -log 10 (H +) The term is used to indicate basicity or acidity of a solution on a scale of 0 to 14, with pH 7 being neutral.
WebbThe pH of a solution is defined as the negative logarithm to the base 10, of the concentration of H + ions in solution in mol dm –3. pH is expressed mathematically as pH = -log 10 [H +] or pH = -log 10 [H 3 O +] Concept: The pH Scale Is there an error in this question or solution? Chapter 8: Ionic Equilibrium - Evaluation [Page 31] Q 13. Q 12. WebbIf pH >7, the solution is basic. The pOH should be looked in the perspective of OH-instead of H +. Whenever the value of pOH is less than 7, then it is considered basic. And …

WebbA solution is basic, if the OH - ions are in excess. Definition of pH, pOH, and pKw: The concentrations of hydrogen ions and indirectly hydroxide ions are given by a pH number. pH is defined as the negative logarithm of the hydrogen ion concentration. The equation is: pH = - log [H +] similarly, pOH = - log [OH -] and p Kw = - log [Kw] .
